[Modified postoperative prevention of recurrence in euthyroid struma nodosa]

In a prospective clinical study after uni- or bilateral subtotal thyreoidectomy, cause of euthyreote goitre, no substitution with L-thyroxin was ordered postoperatively. The follow-up after three months and one year shows a representative time for judgement of the hormonal situation after three months. Over one year 55% with bilateral resection need hormone substitution but only 4% with unilateral. Bilateral subtotal thyroid resection seems to be a too extensive resection to leave enough functional thyroid tissue for a physiological function.
